EDGING MACHINE.

Application filed December 11, 1925.

This invention relates to edging or hookforming machines by means of which a blank of sheet material may be provided with oppositely disposed hooks at its opposed edges for the purpose of subsequent assembling with other blanks to form a body or the like; or for the purpose of forming a body from a single blank.

The main object and feature of the invention is to provide a construct-ion characterized by unusual simplicity and reliability.

In the accompanying drawing, the invention is disclosed in a concrete and preferred -form in which:

Fig. 1 is a transverse vertical sectional view'of a device embodying the invention with parts shown in hook-forming position.

Fig. 2 is a diagrammatic view of the hookforming members shown in Fig. 1 but in the position they occupy before the hooks are formed or before the edging operation takes place.

Fig. 3 is a vertical sectional view in the plane of line 3-3 of Fig. 1; and

Fig. 4 is another vertical sectional view in the plane of line 4 4 of Fig. 1.

1 and 2 indicate the usual hook-forming jaws or edging tools that cooperate with each other and with a support 3 on which a blank rests to clamp and edgeI a blank, the blank being fed into position either by hand or suitable mechanism well-known in the art. As each side of the machine is substantially identical in construction, it will be suiiicient, for the present, to describe the detail features of construction in which the invention is clothed at one. side of the machine. Jaw

2 is mounted on a carrier 4 pivotally sup-n ported at 5 and actuated by means of a cam 6 that engages cam roll 7 connected with carrier 4. Edging tool 1 is mounted on a carrier 8 that is sustained by means of two pairs of parallel links 9 and 10, there being one pair at each side of the carrier 8. One end of these links is connected, as at 11, with the carrier while the other end of said links is connected with pivotal supports 12 on the framework. Considering the left-hand end of Fig. 1, it will be understood that if carrier 8 be reciprocated it will, by reason of serial No. '74,906'.

links 9 and 10, also rise and the resultantmotion will be an oblique one corresponding to the conformation of the edging tools. Any suitable means may be employed for the purpose of reciprocating carrier 8 but, in the present insta-nce, a rotating cam 13 is arranged bet-ween the opposite pairs of links and a. cam roll 14 supported on carrier 8 engages said cam to transmit the urge of the cam to the carrier. As has been explained, when carrier 8 is reciprocated it also rises, or falls as the case may be, and cam roll 14 therefore has a slidable connection 15 with carrier 8 so as to compensate for the rising and falling moven'lent of said carrier. This action can be readily understood by comparing` the right and left-hand end of Fig. 1. Cam 13, as well as cam 6, is mounted on a shaft 16 that extends across the machine and in the space between the pairs of links of each edging device. The blanks are fed into position on supports 3 and are side registered by means of gauges 17 and 18 associated with edging tools 1; and after jaws 2 are closed against supports 3, tools 1 move into an active position, one in an upward direction and the other in a downward direction, thereby at the same time. lifting gauge 17 and depressing gauge 18 against the tension of springs 19 and 20.

I claim:

1. An edging device to form oppositely bent hooks on a blank, including: two carriers, an edging tool on each carrier, means for reciprocating the carriers in unison toward and away from each other, and means to cause one carrier to move obliquely upwardly and the other obliquely downwardly, in response to their own reciprocating movement, including: two pairs of parallel links for each carrier, one pair at each side of each carrier, pivotal connections between each carrier and its links, and pivotal supports for the other end of the links.

2. An edging device including: a carrier. an edging tool lthereon, a .pair of parallel. links at each side of the carrier, pivotal connections between one end of the links and the carrier, pivotal supports for the other end of the links, a rotating cam to reciprocate the carrier, and a cam roll slidably connected With the carrier to engage the cani.

3. An edging device including: a carrier, an edging tool thereon, a pair of parallel 5 links at each side of the carrier, pivotal connections between one end of the links and the carrier, pivotal supports for the other end of the links, a rotatinI cum arranged between the pairs of parallel links to reciprecate the carrier, and a cani roll slidably connected with the carrier to engage the cam.
